Lincoln L-head V12 engine

The Lincoln L-head V12 engine is a flathead V12 that the Ford Motor Company built between 1932 and 1940 for its Lincoln automobiles, in two distinct versions and three displacements. It was introduced as a 65 degree L-head V12 of 447.9 cubic inches (7.3 litres) and 150 bhp, and the following year a smaller, separately engineered 67 degree 381.7 cubic inch (6.3 litre) V12 of 125 bhp joined it, with four main bearings and offset blocks. In 1934 the newer engine grew to 414 cubic inches (6.8 litres) and 150 bhp, replaced both earlier engines and left Lincoln with a single large V12. The 1932 engine allowed Lincoln to split its K-Series into the V8-powered KA and the V12-powered KB. It should not be confused with the much smaller Lincoln-Zephyr V12, a 267 cubic inch 75 degree engine based on the Flathead Ford V8. Ford had acquired Lincoln in 1922, after Henry Leland founded the Lincoln Motor Company in 1917.
